Party wall cavity insulation for Banbridge properties
If your property is in Banbridge or the BT32 district or nearby Newry and Downpatrick, it is within our County Down coverage. It is roughly 32 miles south-west of Bangor.
Most Banbridge houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. If a wall in Banbridge is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Every elevation is judged on its own exposure. Parts of County Down face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
In terms of approvals, in Banbridge inserting cavity wall insulation needs a building control application to the council before work starts.

What we need from you and your neighbour
The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
What is included in Banbridge
- Loft inspection and borescope check
